Hi All

Keep seeing some high usage when Quanta is idle (and when it's not idle).


I don't know anything about QT, and stuff, but strace on a running Quanta is 
providing this ad infinitum:

ioctl(3, FIONREAD, [0])                 = 0
gettimeofday({1173777494, 107926}, NULL) = 0
select(13, [3 5 6 8 10 11 12], [], [], {0, 655400}) = 1 (in [11], left {0, 
655400})
gettimeofday({1173777494, 108020}, NULL) = 0

Ad infinitum
